Embodiment 1
[0028] see Figure 1-5 , the centrifugal fan with a guide structure in this embodiment includes a centrifugal wind wheel and a drive motor 1, and the drive motor 1 is fixedly connected to the centrifugal wind wheel through a transmission shaft 2; the centrifugal wind wheel includes a base 3, a plurality of The blades 4 and the guide structure fixed on the base 3 along the circumferential direction, the guide structure includes a plurality of guide parts 5 uniformly arranged along the circumferential direction, the guide parts 5 are arc-shaped, the The bending direction of the guide part 5 is the same as that of the blade 4; one end of the guide part 5 extends to the center of the base 3, and the other end extends to the periphery of the base 3; from the center of the base 3 to the periphery of the base 3, The height of the guide part 5 gradually decreases.
[0029] see Figure 1-5 , the arc-shaped structure is composed of three-segment structures, and the three-segment struc...
Embodiment 2
[0039] Different from Embodiment 1, the flow guide structure in this embodiment is arranged in a centrifugal fan with a single centrifugal rotor.
